Clamp-on ultrasonic flow measurement

Instrotech has on offer Kobold’s portable DUC-MP and the stationary DUC-MF, designed for continuous flow measurement. They are highly accurate and drift-free operating flowmeters for liquids in filled pipes. The devices are hygienic, leakproof, and monitor all aggressive and toxic liquids without problems. A special advantage is that the ultrasonic sensors are clamped onto the outside of the pipe, so cutting the pipe is not necessary for installation. Similarly, there is no requirement for process shutdown, significantly reducing the operating costs. The robust Quickfix mounting kit enables precise and quick sensor installation. With the Quick Setup option, the transmitter can be configured in less than one minute, and the sensors are mounted onto the pipe in less than two minutes By default, the transmitter operates at medium temperatures from -40 to +150 °C and flow rates of up to 30 m /s. in pipe sizes from DN 10 to DN 6000. DUC works on the high-precision ultrasonic-transit time method. The AND-technology (anti-noise deflector) results in the ultrasonic waves being guided and coupled so that unwanted echoes and signal variations are avoided.
